Zero-Brane Quantum Mechanics

Physical Review Letters (1996)

Daniel Kabat Philippe Pouliot

We consider low energy, nonrelativistic scattering of two Dirichlet zero-branes as an exercise in quantum mechanics. For weak string coupling and sufficiently small velocity, the dynamics is governed by an effective U(2) gauge theory in $0+1$ dimensions. At low energies, D-brane scattering can reliably probe distances much shorter than the string scale. The only length scale in the quantum mechanics problem is the eleven-dimensional Planck length. This provides evidence for the role of scales shorter than the string length in the weakly coupled dynamics of type IIA strings.

Instanton calculations versus exact results in four dimensional SUSY gauge theories

Nuclear Physics B (1995)

D. Finnell Philippe Pouliot

We relate the non-perturbative exact results in supersymmetry to perturbation theory using several different methods: instanton calculations at weak or strong coupling, a method using gaugino condensation and another method relating strong and weak coupling. This allows many precise numerical checks of the consistency of these methods, especially the amplitude of instanton effects, and of the network of exact solutions in supersymmetry. However, there remain difficulties with the instanton computations at strong coupling.

Membrane scattering withM-momentum transfer

Physical review. D. Particles, fields, gravitation, and cosmology/Physical review. D. Particles and fields (1997)

Joseph Polchinski Philippe Pouliot

Membrane scattering in $M$(atrix) theory is related to dynamics in three-dimensional SU(2) gauge theory, with the transfer of ${p}^{11}$ being an instanton process. We calculate the instanton amplitude and find precise agreement with the amplitude in eleven-dimensional supergravity.
